METHOD 01E HANDLING YARN AND MACHINE THEREFOR.

Application filed nil-gust 28, 1919. Serial No. 320,505.

To all whom it may concern:

Be it known that I, ARTHUR L. REMING- TON, a citizen of the UnitedStates, residing at Worcester, in the county of Worcester andCommonwealth of Massachusetts, have invented a new and usefulIn'iprovement in a Method of Handling Yarn and Machines Therefor, ofwhich the following, together with the accompanying drawings, is aspecification. a

My invention relates to a method of handling or preparing yarn and amachine for carrying out the same.

The object of my invention is to provide a new method of handling orpreparing yarn by means of which the yarn may readily be dyed while itis on a spool. A further object of my invention is to provide a machinefor carrying out my method.

In dyeing yarn which is to be wound on a spool, it has been found to bemost desirable to be able to dye the yarn while it is on the spool, asthis procedure saves much labor and insures that the yarn will not bedisturbed after it has once been wound on thespool. To this end, it hasbeen proposed to dye yarn on the spool by placing the spool in a tankfilled with dyeandputting the tank under sufficient pressure to forcethe dye into the yarn. In order that the dye may properly percolatethrough the yarn on the spool, it is necessary that the yarn be woundcomparatively loosely there-.

winding the yarn so that it may readily be dyed under pressure and atthe same time be used on the spool.

By my invention, I propose to provide a novel method and'a machine forwinding the yarn from a standard jack spool onto a dunt my spool, insucha manner that it may be readily dyed under pressure, after which theyarn may be rew-ound on the standard jack spool.

, In the accompanying drawings, Figure 1 is aview in side elevation of amachine for carrying out my method.

Figure 2 is an end view of the machine shown in Fig. 1.

parts in the different figures.

Referring to the drawings, the machine comprises a frame 1 provided atoneend with bearings 2 for r'ota'tably supporting a jack-spool 3. Aguide roll '1 is rotatably mounted at the other end of the frame 1 andis adapted to be driven from a suitable source of power by the pulleys 5and abelt 6, as best shown in Fig. 2. A dummy roll 7 is rotatablysupported between trunnion arms 8 that are pivotally mounted at one endon the upwardly extending projections 9 of the frame 1. The dummy spool7 is thus adapted to rest upon the surface of the guide roll 4: with itsend flanges 10 spanning the same.

The surface of the guide roll' 4 is provided with a plurality ofV-shaped grooves 11, as best shown in Fig. 2, each groove passingentirely around the roll and at an oblique angle with the axis of theroll, the pitch of each groove being equal to the distance between thestrands of yarn, and the number of grooves being equal to the number ofstrands, for a purpose to be hereinafter described. The particular formof the guide rolltforms no part of my present invention, but issubstantially the same 'as the roll shown and described 111 Pat. No.631,867 fora winding machine. The dummyspool 7 comprises a hollowcylindrical shell 12 that is provided with a plurality .o'fperforations13, for a purpose to be herek inafter described. 1

on, and difficulties have been encountered in The pressure between thedummy spool 7 and the guide roll-4 is adapted to be adjusted by means ofa; plurality of weights 14-, that are mounted in side by side relationupon a shaft 15 carried between the legs 16 of the frame 1. The shaft 15is connected to the pivoted trunnion arms 8 by means of links 17 and 18,so that turning of the shaft 15 under the influence of the weights 14will cause the trunnion arms 8 to be moved about their pivots withrespect to the guide roll 1 and thereby regulate the pressure betweenthe guide roll 1 and the dummy spool 7 The weights 1 1 are loose on theshaft 15 and are adapted to be fixed atany given position i i p Ithereon by means of set screws 19. A brake Like reference charactersrefer to like arm 20 provided at one end with abrake shoe 21 adapted toengage the yarn on the jack spool 3, is mounted on a shaft 22 rotatablysupported between the legs 23 of the frame 1. The shaft 22 is providedwith weights 24 for causing the brake shoe 21 to engage the yarn on thejack spool 3 with a pressure which may be varied in the same manner aswith the weights 14-. A handle 25 is also mounted on the shaft 22 forthe purpose of quickly releasing the brake shoe 21.

Having thus described the various parts of my machine the operationthereof in carrying out my method. is as follows z-The jack-spool 3 isfirst wound with the yarn to be dyed, after which the spool is placedbetween the bearings 2 and the brake arm 20, so adjusted by means of theweights 2% that the brake shoe 21 will exert an appreciable pressureupon the jack spool winding. The empty dummy spool 7 is then placedbetween the trunnion arms 8 and the weights 1-1 are so adjusted on theshaft 15 as to cause a slight pressure between the dummy spool 7 and theguide roll 4. The yarn 2G is then led from the jack spool 3 over theroller 27 to the dummy spool 7, after the strands thereof have beenplaced in the grooves 11 of the guide roll 4. The guide roll l is thendriven, which in turn drives the dummy spool T and causes the yarn to beWound thereon. As the yarn is being wound, the grooves 11 cause atraversing movement of each individual strand, thereby preventing agiven strand from occupying the same position on the dummy spool 7during two successive revolutions of the spool 7. As the dummy spool 7engages the guide roll l with only a slight pressure the resultingwinding upon the spool 7 will be comparatively loose and considerablylarger in diameter than the original winting that was upon the iaclrspool 23. Furthern'iore, the traversing movement of the individualstrands of the winding results in a winding upon the spool F that ismore or less open. After the yarn has been transferred from the jackspool 3 to the dummy spool 7, the spool 7 is removed from the machineand is placed in the pressure dyeing tanlr. The perforations 13 permitthe dye to percolate through the yarn quite easily.

After the yarn on the spool 7 has bee dyed and allowed to dry, it isready to be rewound. The empty jack soool 3 is then placed between thetrunnion arms 8 and the dummy spool '7, with the yarn thereon, is placedbetween the bearings 2, thereby reversing the former positions of thespools. The weights 14: are then set so that inaxi mum pressure will beexerted. between the jack spool 3 and the guide roll l, as indicated indotted lines. The PTPSSHTG exerted by the brake shoe 21 upon the windingof the dummy spool 7 is also increased. The yarn is then rewound uponthe jack spool 3 in the same manner as previously t escribed. and as thepressure under which the yarn is wound is greatly increased, it isobvious that the winding will be much tighter and will be substantiallythe same diameter as the original winding upon the incl: spool 0. Thejack spool 3 with the dyed yarn wound tightly thereon is then ren'iovedfrom the machine for further use.

From the foregoing it is apparent that the use of my method and of mychine, it is possible to wind yarn fro; standard jack spool upon a dummyin such a manner that it may be readily dyed by the pressure method. Inaddition, by my machine, it is possible to rewind the yarn, after it hasbeen dyed, upon the ori inal jacl: spool, in such a manner that it willhave the same com )actncss as the original winding.

l Vhile l have shown my method as being carried out by a specific typeof machine, it is obvious that it is not so limited, but may as well becarried out by different machines which may be designed to carry out thesame method. I desire therefore that only such limitations be imposedthereupon as may come within the scope of the appended claims.

I claim,

1. A method of preparing yarn which consists in first winding yarn upona jack spool, then loosely rowinding the yarn upon a dummy spool withsuperimposed layers of yarn crossing each other, then dyeing the yarn onthe dumn'iy spool and finally in. rewinding the yarn compactly upon thejack spool.
